To all whom, t may concern:

Be it known that I, FREDERIC COBLYN, a citizen of the Kingdom of Belgium, and a resident of Seraing, Belgium, have invented certain new and useful Improvements in Railway-Chairs, (forwhich I have obtained Letters Patent in Belgium, dated February 19, 1886,

No. 72,053; in Germany, dated March 28, 1886, No. 37,491; in England, dated September l, 1886, No. 11,146; in Austria-Hungary, dated April 24, 1886, No. 19,852; in Spain, dated April 14, 1886, No. 9,214; in France, dated March 23, 1886, No. 174,959; in Luxemburg, dated April 21, 1886, No. 675; in Italy, dated January 24, 1887, No. 21,149 480, and in Portugal, dated April 18, 1888, No. 1,262,) of which the following is a full, clear, and exact specification.

Referring to the drawings, Figure 1 is a vertical transverse section of a portion of a metallic tie and rail and my improved railfastening devices. Fig. 2 is a horizontal section on line :n of Fig. 1, and Fig.3 is a side elevation, the tie being shown in section.

The invention relates to railway-chairs, and to means for securing the rail thereto and to the tie, and has for its object, not only to provide a secure fastening for the rail, but also to provide means for readily disconnecting the rail and replacing it when this becomes necessary.

The invention consists in the combination, with the tie and rail, of a chair of peculiar construction, a shoe, and a wedge, substantially as hereinafter described, and as set forth in the claims.

In the drawings, T indicates the tie, presumed to be of metal, though of course the ordinary wooden tie would answer as well.

C is the chair, whose bed-plate c is made tapering in the direction of the center of the track, and from which projects an abutment C', that has approximately the form of a truncated pyramid, and in clines in the direction of the rail R, which may be of any usual pattern.

Sis a shoe, constructed in the form of a housing, and fits over the abutmentand nearly incloses the same, except a portion of the outer face thereof. The shoe has a 'central vertical and semicylindrical groove s,formed in the outer face of its inner Wall s, for purposes presently explained, and said wall is of such height or length as to extend down to or nearly to the bed-plate of the chair.

P is a retaining or clamping plate bolted to the bed-plate c of the chair and to the tie T and overlaps a portion of the inner half of the foot of the rail R, and NV is a wedge driven between the web r of the rail and the shoe S, and constitutes the means to lock the parts together. It is obvious that by driving out the wedge W the shoe S can be lifted olf the abutment C of the chair and the railfoot then slipped from under the retaining or clamping plate, thus providing a rail-fastening which affords the facility of removing the rail without disturbing the chair or its fastenings. Vhen a wedge of wood is employed and tightly drivenbetween the shoe and web of the rail, it will expand into the semicylindrical groove s', formed in the inner face of the shoe, and thereby prevent its working loose, while if a metallic wedge is employed said Wedge may be provided with a like groove and a bolt inserted into the hole so formed to prevent longitudinal displacement of the wedge.

As more plainlyshown in Fig. 1, the lower end of the shoe S extends downward sufficiently far to lie against the foot of the rail, thus holding the latter against displacement toward the abutment of the chair should the Wedge 1V accidentally Work loose. The object of forming the inner face of the abutment inclined relatively to the web of the rail is ,to lock the shoe against vertical displacement, the inner wall of said shoe increasingin thickness from the cap S2 or upper Wall downwardly;

4and to more securely fasten the rail to the tie The object of forming the base or bed plate of the chair tapering is to give the tread of the rail R a slightinward inclination. This may, however, be effected by a proper construction of the tie or by interposing a wedge-shaped plate between the chair and tie. It is ot' course a great convenience of construction to provide the chair with a bed-plate, yet this may be -dispensed with and the abutment C and clamp P bolted separately to the tie, while instead of the clamp spikes may be used with Wooden ties. On the other hand, the abutment may be of cylindrical form, the shoe S being constructed accordingly, so as to accommodate itself to this form.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, substantially as herein described,with a tie, a rail, and fastening devices for confining the rail-foot to the tie on one side of the rail, of an abutment projecting from the tie on the opposite side, a shoe adapted to it onto said abutment and having its face proximate to the rail inclined, and a wedge adapted to be driven between the web of the rail and the shoe, for the purpose specified.

2. The combination, substantiallyas herein described, with a tie, a rail, and fastening` devices for confining the rail-foot to the tie on one side of the rail, of an abutment projecting from the tie on the opposite side, a shoe adapted to fit onto the abutment and having its face proximate to the rail inclined and abutting against the rail-foot, and a wedge adapted to be driven between the web of the rail and the shoe, for the purpose specified.

3. The combination, substantially as herein described, with a tie, a rail, andl fastening devices for confining the rail-foot to the tie on one side of the rail, of an abutment projecting from the tie on the opposite side of the rail, a shoe constructed to fit onto the abutment, said shoe having` its face proximate to the rail inclined and provided with a vertical groove or recess, and a wedgeadapted to be driven between the Web of the rail and the shoe, for the purpose specified.

4. The combination, substantially as herein described, with a tie, a rail, and fastening devices for confining the rail-foot to the tie on one side of the rail, of an abutment projecting vertically from the tie on the opposite side of the rail and having its face proximate to the rail inclined, a shoe constructed to fit on said abutment and increasing in thickness downwardly, and a wedge constructed to be driven into the space formed between the inclined face of the shoe and the vertical face of the rail-web, for the purpose specified.

5. The herein-described rail-chair, comprising a base-plate, an abutment projecting vertically therefrom and at right angles thereto, in combination with a detachable ,shoe constructed to iit on the abutment an'd having its outer face inclined, substantially as and for the purpose specified.

6. The herein-described rail-chair, comprisingabase-plate gradually decreasing in thickness and an abutment projecting vertically therefrom and at an angle thereto, in combination with a detachable1 shoe constructed to tit onto the abutment and having its outer face inclined, substantially as and for the purpose specified.

7. The herein-described rail-chair, comprising a base-plate provided on one side with a clamping-plate and on the opposite side with an abutment projecting vertically from and at an angle to said base-plate, in combination with a detachable shoe constructed to fit on the abutment and increasing in thickness downwardly, substantially as and for the purpose speciiied.

8. The herein-described rail-chair, comprising a base-plate provided on one side with a clamping-plate P and on the opposite side with an abutment having the form of a truncated pyramid and projecting vertically from an d at an angle to said base-plate, in combination with a detachable shoe S, constructed to fit on the abutment and increasingin thickness downwardly, substantially as and for the purpose specified.

9. The herein-described rail-chair, comprising a base-plate P on one side thereof, an abutment C on the opposite side projecting vertically from and atan angle to the baseplate, in combination with the shoe S, constructed as described and provided in its ,outer face with a vertical groove or recess,

substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of July, 1887. FREDERIC COBLYN. Witnesses:
